挥发油作为藿香的药效成分,积累并储藏在腺鳞中。以胡薄荷酮型藿香的叶片为材料,对藿香不同生长时期的叶片进行形态学观察,并通过GC-MS检测分析腺鳞中的挥发油成分。同时采用qRT-PCR技术测定挥发油中单萜生物合成途径中关键酶基因的相对表达量。结果表明,藿香腺鳞的密度呈现先下降后趋于平稳的趋势。随着藿香叶片的不断生长,腺鳞中胡薄荷酮的相对含量由79.26%降至3.94%(89.97%~41.44%),而异薄荷酮的相对含量则由2.43%上升至77.87%(0.74%~51.01%),其他成分的变化相对不明显。单萜类成分相对含量与其关键酶基因相对表达量的相关性分析表明,薄荷酮、异薄荷酮的相对含量与胡薄荷酮还原酶(PR)的相对表达量存在显著的相关性(r>0.6,P<0.01)。综上所述,该研究揭示了藿香腺鳞内含物的主要成分的积累规律及其生物合成关键酶基因的表达规律,为藿香药材合适采收时期的确定及质量控制提供了科学依据和数据支撑,并初步揭示藿香中以胡薄荷酮和异薄荷酮为主的单萜类成分的生物合成机制,为后续研究藿香中单萜类成分合成积累的分子机制的深入研究奠定基础。
